Is there calcium in our water?

Yes. Calcium levels in water do not pose a health risk; in fact calcium uptake from various sources is typically beneficial. However, sunlight can interact with small amounts of calcium that are in the water and sometimes leave a slight stain on vehicles or elsewhere. We suggest washing your car undercover or in the shade to avoid this occurring, though stains can be easily removed by applying an equal mix of white vinegar and distilled water with a soft cloth.
